Minecraft‘s Realms servers have been down for most of the past four days. Mojang’s official account for reporting service status updates noted that “intermittent failures or slowdowns” began on August 13th, and despite similarly intermittent reports of uptime in the days since, the servers remain inaccessible to most players today.
Realms is a paid subscription service that grants access to a private multiplayer server for Minecraft‘s multiplatform Bedrock Edition. It lets between three and 10 players (depending on subscription tier) join the same Minecraft world, with the owner able to install mods from Minecraft‘s paid marketplace.
